Abstract
This exegesis takes a critical look at the performance paradigm of sound diffusion. In
making a shift away from the sixty-year-old practice of performing on a mixing desk or
other fader bank console, it proposes and outlines a goal towards intuitive and transparent
relationships between performance gesture and spatial trajectories. This is achieved by a
coupling of the two previously segmented fields within electroacoustic: spatialisation and
interface design. This research explains how connections between the two fields and an
embracing of contemporary technological developments, with a goal toward increasing
the liveness and gestural input that currently limit sound diffusion practice, could extend
the art form into a virtuosic and compelling gestural performance art. The exegesis introduces
and describes the author’s research and development of tactile.space, a new multitouch
tool developed on the Bricktable for live sound diffusion. tactile.space is intended
as a contribution to the growing research area of user interfaces developed specifically for
the performance of sound in space. It affords performers a new level of gestural interaction
with the space of the concert hall and the audience members and redefines multiple
standardised interactions between the performer and the space, the gesture, the audience,
and the sound in a diffusion concert.
